SHELL AND METHOD DF MAKINGTHE SAME.

SPECIFICATION forming part of Letters Patent N o. 3481.788, datedSeptember 7, 1886.

Application filed April 8. 1586. Serial No. 198.252. (No model.)

' State of Massachusetts, have invented a new and ImprovedHollowaProjectile or Shell for Great Guns and otherFire-Arms; and Ihereby v declare the following to lbe afull, clear, and exactdescription ofthe same", reference being hadto the accompanyingdrawings, making part of this speciticatiom' in which- Figurel is a sideelevation of the tubular .or cylindrical blank to be used inmakin'g myimproved shot or projectile. "'iiig. 2 is a perspective view of theprojectile partially in section. Fig. 3 is a lon 'nal seetienal View ofj the same, with the ncharging hole in the base of the projectile.Fig.`4 is a longitudinal sectional view showing the charging opening inthe point. Fig. is a perspective view of a shell-blank. Fig. 6 is ashell made from said blank. Figs. 7 and 8 illust-rate shrapnel-shellsaccording to my invention.

My invention relates to hollow projectiles, especially'those designedfor great guns; and it consists in a shell or projectile made from atbulablank and brought to shapeby meansl of dies, such as are shoven anddescribed inmy application for a patent filed March 24, 1885, Serial No.160,016, the method therein employed being also the method employed topro- ,duce' the shell described in this application.

In order that those skilled in the art may make and use my invention, Iwill proceed to describe the manner inwhich I have carried -it out.

-I take a'tubular blank, a, Fig. 1, and, after properly heating it, passit between dies, as described in my application hereinbefo-re mentioned,and close down one end, b, and weld it together so asto form a point,and simultaneously therewith break down the base, d, in the manner shownin Fig. 3, ieavng a small charging-opening, e. This opening e alsoaffords means for inserting a fuse.

When it is desired that the shell shall be 'a percussion-shell, the based (see Fig. 4) is closed down entirely and wel'ded,`while the I claim asnew, and desire to secure 4 made for penetration.

I show in Figs. 7 and 8 a further no'dication, adaptedfto be usedasshrapnel, and provision made for an opening in the base or point ofthe projectile sufliciently large to enable the placing oi theshrapnelslhargesvifhin the'slrel.'

I am aware that heretofore solid and hollow projectiles have been-madeinto form by castl ing, drop-forging, and ways otherwise than by v,rolling, and afterv being formed were subjected to a rolling operationto condense andharden the metal, while my invention provides a pro- Yjectile which is, by a rolling operation, simultaneously brought to formand condensedand hardened, such simultaneous operation being,distinguishable in the projectile 4by the forging-lines on the surfacebeing spiraly to the axis of the projectile, .while the hardeningandfinishing lines are at right, angles to thesaid axis.

Having thus described my invention, what by Letters Patent, is- Y.

1. A hollow projectile rolled to' form and the metal condensed andhardened all at'one operation, substantially as set forth.

2. The method of making a hollow .project il'e or similar structure,consisting vin rolling a tubular blank, thereby drawing one end to-Vgether to `form the forward end of the projectile and thickening andcondensing the walls of the projectile at the same time, substantiallyas described.
